APPARATUS AND METHOD FOR FEEDING INOCULANTS INTO A FLOW OF MOLTEN METAL AND AUTOMATIC MOLTEN METAL POURING MACHINE

WIPO Patent Application WO/2011/004685

A1

Disclosed are an inoculant feeding method and apparatus, wherein a desired amount of inoculants can be fed into a molten metal poured into a casting die by an automatic molten metal pouring machine, and an automatic molten metal pouring machine using the apparatus. An inoculant feeding apparatus (1) feeds inoculants into a molten metal poured into a casting die (2) from an automatic molten metal pouring machine (20), at a predetermined rate corresponding to the amount of the poured molten metal which gradually varies. The apparatus (1) is provided with a hopper (8) which is attached to a carriage (6) and which stores the inoculants, a screw conveyor (9) attached to a lower end of the hopper, a drive mechanism (10) which is attached to a base end of the screw conveyor and which drives the screw driver, and a controller (30) which controls the drive mechanism. Due to the control by the controller (30), the screw conveyor (9) is driven through the drive mechanism (10), corresponding to the amount of the molten metal poured from the automatic molten metal pouring machine (20) whereby the inoculants are fed from the screw conveyor (9) into the molten metal poured into the casting die (2) from the automatic molten metal pouring machine (20).
